This invention appertains to new and useful improvements in harvesting machinery and more particularly to a loader for green pea vines, hay, etc.

The principal object of the present invention is to provide a loader of the character stated in which novel pick-up meansis provided for practically picking up cleanly all material that is to be loaded.

Another important object of the invention is to provide a loader of the character stated which is positive acting and not susceptible to the ready development of defects.

These and other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a fragmentary top plan view of the apparatus.

Figure 2 is a fragmentary side elevational view.

Figure 3 is a longitudinal sectional view through the first elevator showing the novel pickup means.

Figure 4 is a fragmentary elevational view of the drive means for the elevators.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to a conventional tractor, which is of the type having a rearwardly extending platform 8.

This harvester includes a rearwardly extending and inclined elevator I and a transversely extending and inclined elevator generally referred to by numeral 8. The elevator I dumps material onto the short horizontal conveyor generally referred to by numeral 9 and the material is taken from the conveyor 9 and lifted by the conveyor 8.

Under the rear portion of the elevator I is a shaft III which also extends under the platform 6 and is equipped with ground engaging wheels ll.

As is clearly shown in Figures 1 and 4, the shaft I carries a gear l2 which meshes with a gear l3 on a counter-shaft M. on thiscounter-shaft M is a sprocket wheel l over which is trained a sprocket 'chain l6 extending from a sprocket wheel lI located on a second counter-shaft l8 located below the upper end of the elevator I just beneath the shaft l9 which drives the endless,

conveyor 20 of said elevator I.

- The shaft l8 carries a bevel gear 2| meshing sprocket chain 26, this chain being also trained over a sprocket wheel 21 located on the said upper shaft l9. Thus the axle Ill drives both conveyors and 24 of the elevators I and 8, respectively. It can be seen that the shaft 23 be sides driving the short horizontal conveyor 9, ac-

tually drives the conveyor 24 through the medium of a sprocket chain 28 and corresponding sprocket wheels.

An important feature of the present invention is the pick-up means generally referred to by numeral 29. This pick-up means is located at the lower end of. the elevator I and consists of .an elongated cylinder 30 having a plurality of the elevator I has wheels 34 mounted on an axle 35 and this axle serves to drive the cylinder 30, and the drum 33 through the medium of gears 36. It can be seen that the drum 33 with its spikes or fingers 32 rotates and lifts the pea vines or other materials'from windrows and moves the vines to the cylinder which is rotating and obviously the fingers leave the vines as the vines reach the cylinder 30 and pass downwardly with a bevel gear 22 on a shaft 23, which shaft 23 operates to drive the conveyor 24 of the elevator 8. The shaft l8 also has a sprocket wheel 25 thereon over which is disposed a vertically extending through the grooves 3| in the cylinder 30 with the result that there can be no entanglement of the fingers with the vines. The cylinder 30, in turn, as it rotates, feeds the material onto the conveyor 20 and it is elevated to be discharged into the box in which the horizontal conveyor 9 is located and from there, it is taken up by the elevator 8 and dumped into a suitable take-away conveyance.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the, invention as claimed hereinafter.

' Having described the invention, what is claime as new is:

1. In a harvester, an elevator, ground engaging wheels at the lower end of the elevator, an axle driven by the wheels, a pick-up mechanism at the lower end of the elevator and adjacent the axle, said pick-up mechanism being adapted to be driven by the said axle, said pick-up mechanism consisting of a drum having a plurality of fingers extending outwardly therefrom and drive means between the axle and the said drum, and a cylinder having a plurality of circumferentially extending grooves for receiving the fingers of the drum, said drive means being adapted to simultaneously drive the drum and cylinder in the same direction.

2; In a harvester, a pick-up assembly, a conveyor, said conveyor including a web and a driven roll, said pick-up assembly consisting of a drum having a plurality of fingers radially disposed therefrom, a cylinder disposed in close parallel relation with respect to the drum and having circumferentially extending grooves in which the fingers of the drum are movable, a drive connection between the cylinder and the drum, and a drive' connectionbetween the conveyor roll'and the cylinder.
